Is This The Oil Pressure Sensor/switch?

2016 Bonneville T100; air cooled/EFI


I want to locate the oil pressure sensor or switch (whichever it may be).

In a post on another forum from January 2015, it’s referred to as a “switch”:


"the low pressure warning light switch is located in the upper crankcase behind the cylinder head … it's a single wire switch …”


I’m attaching a picture from just behind the cylinders - 2 components: A & B.


Can someone please identify both A & B?

 

I have discovered the answers to my questions and here post updated pics.
